is claims. (o1. .issn-25) vThis invention relates to an exercising machine of theitype in v which a motor means is adapted to move limb `exercising members for moving the limbs `of-fa lperson applied to parts of the limb exercising members. vMachines of the particular class `are Well-known in the art, and in the main, comprise an `electric motor that moves pedals or levers for moving the arms and legs ci a person using the machine.

In the machineof the prior art, the limb exercising members are moved in predetermined cycles, and With no variation in the movement of thelimbe'xercisingmembers relatively to one'am other. In this Way, there is Vpreserved a constant rhythm of movement that is easily anticipated anddetraots from the exei'cisingivalueof the prior art machines. `It is'theobject of -my invention to contribute an exercising machine in which the l'irnb exercising members move relatively to one another in varying relationship while moving' to exercise the limbs of `the person using the 4fma-` chine.

As va feature of the invention, I utilizelimb exercising members `that are movable by motor means relatively to one another in varying relationship, while movable individually to exercise the limbs of a body.

As a more particular feature of ythe invention,

the limb exercisingmembers are each movable through predetermined cycles, with the relationn ship of the cycle of one limb exercising member to thefcycle of the other limb exercising member being Acontinuously*varied.

VAs a vmore particular feature of the invention, I provide an extremely novel Yand simple means for moving the limb exercising members cyclically,

While `at the same time. `moving the said members relatively to .one another in varying relationship. f

Even more particularly, for contributing the par ticular features set forth, I :utilize a single op` erating .gear member, `Whichpreferably is .aworm,

in Vcontact with -two different gears `that in :turni operate the limb exercising members.l

fl have `thus outlined rather broadly `thefmore important features of my .invention :in order-thated hereto. "'l'hosefskilled inthe art will appre-` ciate that the conception on which my disclosure is :based may readily ybe utilized as a basis for the designing :ofwother structures J for .carrying ont the l 2 l several .purposes of my invention. Itis important, therefore, that the claims to be granted me shall belof -suiflicient breadth to .prevent the appropriation roi fmy 'invention .by thoseskilled in the art.

. Referring now more particularly tothe drawingsthe iframe of my machineis preferably vconstructed of a strip `of steel having spring-like qualities and designated generally by reference numeral le). Welded or bolted to the strip of steel if! at il, are .cross legs l2 that form an .adequate support for .the machine, resting on the floor Ior ground, `as is .quite apparent. The upper portion of the steel strip l0 has secured -theretoiat I3a suitable .bicycle type seat I4 `on which `sits the personto be exercised.

The steel strip -|.0 is bent tat |5Ato form a means for securing a bearing sleeve i6, best shown in Fig. 3. This bearing `sleeve I `is `secured relatively to the bent portion t5 of ythe steel strip Ill through means ,cfa bracket il bolted at I8 `tothe steel strip t0. As seen in Fig. 3, the bearing sleeve I6 .has mounted therein for free rotation .a pair 0i shafts I9, each grooved at 20 for a retaining stud 2l threaded into the bearing sleeve VI-6, Iand retaining the said shafts I9 against endWise removal from the bearing sleeve i6. Itis, of course, appreciatedA that each of the shafts i9 is permitted to rotate-freely in the bearing sleeve i6,

though-prevented against endwise removal there-` from.

Each ci the shafts It is provided with a diametric bore 22, .and secured in `the bore 22 ofthe right handshaft 'it .of Fig. 3 is a limb ,exercising member or lever `2.3.. The lever `23 is ilxed to .the`

`.The vleft .hand shaft .i9 of Fig. 3has iitted in its bore 422 a leVerZSd also secured thereto by astud Maslmila-r to stud 24 `of the right hand shaft i9.'V

At 'the .upper end of each of the levers 23, 23a

there is `-secured a hand grip member 25 of Ua! typeknown well in this art. At the lower end ofi each of the levers 2.3,3230J there is secured a-bicycle type '.pedaltZE on which .are applied the feet of the person being exercised. The pedals 26 `may be .secured `relatively to anyone -of the series lof openings '2.1 formed inthe levers 2'3, 23a. It vwill be recalled that the said levers 23, 23a may also be moved relatively to the shafts I9, thereby making it possible to adjust the machine for persons of different size.

Mounted on the bottom of the steel strip l under the seat I4, through suitable means, is an electric motor M adapted to rotate a worm gear within a gear case 3l. The worm gear 30 is adapted for engagement with a ring gear 32 and a ring gear 33, the ring gear 32 having sixty teeth while the ring gear 33 has fifty-nine teeth. The ring gear 32 is suitably secured within the gear casing 3| to a shaft 34, and keyed to this shaft 34 at 35 is a crank 35. Crank 36 is pivoted at 31 to a connecting rod 38 that is in turn pivoted at 39 to the lever 23. It is obvious that the pivot point 31 may be changed by utilizing any one of the series of extra holes 40 formed in the crank 35. The transmission of motion to the lever 23 by connecting rod 33 may further be changed by utilizing one of the openings 21 other than the particular opening utilized in Fig. 1.

The left hand ring gear 33 is secured within the gear casing 3| to a shaft 4| having keyed thereto at 42 a crank 43. Crank 43 is in turn pivotally secured to a connecting rod 44 at point 45. The connecting rod 44 is then secured at 46 to the limb exercising lever 23a. It is obvious that the drive of lever 23a is exactly the same as that of lever d3 except that one of the levers will -be moved at a speed somewhat higher than that of the other lever because of the variation in the number of teeth of the two ring gears 32, 33.

Due to the extremely simple arrangement just described, it is obvious that each of the limb exercising levers 23, 23a will be moved in a cyclic path, but that the movement of one of the levers relatively to the other will change constantly from cycle to cycle. In this way there will be a constant changing of the relationship of the movement of the two feet of the person sitting on the seat I4 and also of the two arms of the person sitting on the said seat.

I have actually constructed and operated a machine in accordance with the drawings of this application, and have found it extremely satisfactory and desirable, contributing exercising motion to the body that is of extreme therapeutic value.
